A spring 37 is secured to a pin 38 on the tin at one end and at the other end to the free extremity of pawl 36.

At its rear end the pawl 36 is pivotally secured by a screw 36 to a bracket 39 which is fixed to plate 11 and forms a guide for bolt 35. The bolt has at its upper side a pin 40 (Fig. 6) limiting its movement in the direction toward the keeper 41. A spring` 42 (Fig. 3) located between the tin 33 and the shoulder formed at the junction of the extension 34 with the body of the bolt normally holds the bolt in projected position.

About midway between its ends the plate 11 carries a bracket in the form of a bridge 43. The shaft 17 is journaled at one end in this bridge and is supported at the other end by a spindle having a reduced end entering a cavity at the inner end of shaft 17 the spindle supporting an inner knob 44.

Shaft 1'? supports a plate 45 oscillating therewith said plate being loosely mounted and readily removable. llhen the plate is reversed from the position shown it serves as a guard to prevent entry of dirt or other material or objects through the coin slot as in transit or in storage. `When in the position shown it has no edect on the action of the lock.

At the inner side of bracket 43 a plate 46 is mounted on shaft 17, this plate serving as a shutter for the coin-slot and having at 46 a pin and at 47 a slot adapted to register with the coin-slot 19 in one position of the plate. ft is so mounted that in its extreme position (Fig. 4) its lower edge rests on the edge of bracket 43 thus limiting the movementof plate 46 in this direction. lts rearward movement is limited by engagement of the inclined lower edge portion 48 (Fig. 4) with bracket 43. A spring 49 serves to retract the plate 46 on the shaft 17. A pin 32 on the plate engages in the slot in arm 29 to operate the counting device and also rides under the lower surface of pawl 36 to lift it until theA pin comes opposite the notch at 51 (Fig. 5) whereupon the pawl drops into locking engagement with plate 46.

An actuator 52 in the form of a rockarm (Fig. 7) is fixed to shaft 17 for oscillation therewith. The actuator has two arms 535 54 separated by a slot 55. The arms have lugs 56, 56 coacting to support a coin on the inclined face of the actuator and a notch 57 in arm 54 provides clearance for the pin 46 on plate 46 next to the slot 47. The bolt has depending` arms 59 and 60 (Fig. 6) adapted to move through the slot 55. A spring acts on shaft 1'? to hold the actuator in the position shown in Fig. 3.

The shaft of the knob 44 carries a rockarm 61 lying parallel to the actuator 52 and in contact with the inclined under side thereof when the latter is in its normal inclined position and in contact with said actuator for a considerable part of its length in the illustrated embodiment of the invention. The shaft 17 and the spindle of knob 44 are coaxial so that such engagement persists in all positions of the parts. The upper end of the arm extends into a lateral notch at 62 on bolt 35 in position to force the bolt back while at the same time the actuator is moved in the sa'me direction. The parts are so proportioned and arranged that the coin will not only be released but also will be forced out of operative position by arm 60 which normally has its upper or lefthand face in the same plane as the left-hand fa'ce of actuatorr52 (Fig. 3) but which advances ahead of such face in operation (Fig. 5). At the same time also a pin 63 projecting perpendicularly toward the front of the lock and here shown as mounted on a lateral extension of rockarm 61 acts against the lower cam surface of tail 64 of pawl 36. 'lhe knob 18 turns shaft 17, plate 45 and actuator 52 whenever it is moved7 irrespective of the presence of a coin. The knob 44 turns independently of knob 1S and oscillates the rockarm 61. 1f there is a coin on the actuator7 the bolt 35 and the plate 46 move. with knob 18 as do parte actuated by plate 46; but a full movement of knob 44 always rocks actuator 52 and pawl 36, while the bolt is retracted by the upper end of rockarm 61, the movement of the actuator being less in this case than when it is rocked through the medium of the pawl 18. rlhe bolt 35 has a movement of translation imparted to it by the arm 61 suoli that it travels ahead of the actuator 52 by reason of the greater distance of the bolt from the center of oscillation7 by reason of which an equal arcuate movement will result in a greater movement of translation than at points nearer said center.

In the operation of my device, the parts being in the position of Fig. 3 a com is inserted through slots 19 and 4T. 1f the coin is of insutiicient size it will pass down the inclined face of the actuator without effeo-t, the relatively higher position of the rear lug 56 a's compared with lug 56 aiding in this selecting action and the righthand face of arm 59 being so spaced as to facilitate egress of thin coins. The finger 59 is spaced from the face of the actuator 52 far enough so that a coin of insuliioient thickness cannot be used to operate the device as by lodging on the lug 56 and the lug at the lower end of the finger, but will slide down the face of the actuator into the coin boX, it being understood that the coin must be small enough so as not to lodge on the two lugs 56 and 56, e. g. a nickel or a penny. Should the coin be of proper size and thickness it will be arrested on the inclined face by lugs 56, 56. The knob 18 being turned the actuator will act through the coin against arm 59 to retract the bolt and also through the coin against the pin 46 to move plate 4:6 to the. left so as to close slot 19. The movement of plate 4G through pin to lift pawl and to swing roclarm 29, thus actuating the counter and when the pin reaches slot 5l locking the plate against return movement, spring 37 drawing the pawl down against the shoulder on iin 33.

"he coin is now held on the actuator by the force of the spring on extension 3l of the bolt and the coin-slot is closed, all as indicated in Fig. il; therefore shaft 17 may be rocked back and forth until the bolt is released and the door opened. On closing the door the bolt is forced back and releases the coin either permissively by the movement of arm 55) from the face of the actuator or positively by the push of arm (30. he bolt is now free from external control but may be moved by operating knob il at the inner side of the door. rl"he shutter t6 still closes the coin-slot.

`When the lznob el is turned as explained above, the actuator' 52 is moved in a direction to release the coin if it were still in position, the bolt is retracted, the pawl is withdrawn from pin 32 against the tension of spring 3T and the shutter is thrown back by its spring llfl thereby also returning the roclrarin 29 to place and completing the counting action. lf the door should stiel: the bolt may be retracted repeatedly by turning knob Liet.

it will be evident to those skilled in the art that my device may be modified in various respects and may be applied to various uses without departing from the spirit of the invention the true scope of which is indicated in the appended claims, and therefore l do not limit myself 'to the specific embodiment shown in the drawings and described in the specification but only as indicated in said claims.
